Planet Earth II: Deserts is a film presented by David Attenborough and the BBC. The world's deserts are lands of extremes that force animals to come up with ingenious ways of coping with hostile conditions, giving rise to the most incredible survival stories on earth. Watch A pride of desert lions are so hungry they risk hunting a giraffe several times their size, whilst male sand grouse fly nearly 200 kilometres each day from their nests to the nearest waterhole, simply to collect water for their chicks – and when they arrive there are predators waiting for them. And, never filmed before, a tiny bat takes on one of the world's deadliest scorpions just to get a meal.
